LINOTYPE AND INTERTYPE.

Specification of Letters Patent.

Patented Feb. Ill, I919.

Application filed September 25, 1917. Serial No. 193,070.

\ specification.

This invention relates to new and useful improvements in a safety attachment for linotypes.

The object of the invention is to provide an attachment of the character described, which will operate automatically to stop the matrices in the intermediate channel, and before they reach the mold disk, in case they have been improperly assembled in the assembling elevator. In operating a linotype, the matrices are first assembled in the assembling elevator and some of these matrices are capable of being assembled in two positions, that is, in upper or lower position. If the matrices are 14 point or smaller, they should be assembled in lower position so as to aline with the mold disk when carried into position for casting. If they do not aline with said disk, the casting metal will not be projected directly against said matrices, and an imperfect casting will result; and furthermore the heated metal will escape, causing what is known as frontoverflow or front squirt.

It is the object of this invention to provide an attachment of the character described which will automatically stop the matrices in the intermediate channel before they reach the molding disk, in case they have been assembled in the wrongposition in the assembling elevator and when the matrices have been so stopped, they can be then adjusted to lower position before they are sent on throughthe intermediate channel to the molding disk of the linotype.

With the above and other objects in view,

the invention has particular relation to certain novel features of construction, opera tion and arrangement of parts, an example of which is described in this specification and illustrated in the accompanying drawings, wherein;

Figure 1, shows a side elevation of the vise cap of a linotype, showing also the intermediate channel associated therewith.

Fig. 2, is a plan view thereof.

Fig. 3, is an end elevation, showing the safety attachment in locked position.

Fig. 4, is a fragmentary end view of the delivery channel showing the safety attachment in neutral position.

Fig. 5, shows an enlarged fragmentary end view thereof, with the safety attachment in active position.

Fig. 6, shows an enlarged plan view of the first elevator, filling piece, showing also a fragmentary view of the safety attachment.

Fig. 7, shows a fragmentary sectional view of the vise cap, showing the safety attachment in locked position, and

Fig.8, is an enlarged view of the intermediate channel showing the spring and locking pin.

Referring now more particularly to the drawings wherein like numerals of reference deslgnate similar parts ineach of the figures, the numerall, indicates the first elevator filling piece, which is hinged to the top of the vise cap 2 by means of the hinge 3. These parts are common to linotypes. The matrices 4 are assembled in an as- .sembling elevator, the same being a well piece 1 is a U-shaped member 2' which rests in said groove when said filling piece is in active position.

Secured to the vise cap 2 and opposite the exit end of the intermediate channel 13 is an upstanding brace 7 The upper and lower ends of this brace have hearings, in which the actuating rod 7 operates, the lower end of said rod being turned laterally and forming an arm 6. and the upper end thereof being formed into a curved finger 8. One of the channel rails of the intermediate channel 13 has a bearing 10', and also has a flat spring 9- secured thereto at one end, the other end of said spring carrying the pin 10 which projects into said bearing 10', but normally does not project beyond the inner surface of said channel rail. When the fill ing piece 1 is thrown into active position,

" to pass on to the mo the U-shaped member 2 rests against the arm 6, causing a partial rotation of the rod 7, and carryingthe free end of the finger 8 against the free end of the spring 9, forc ing the pin 10 inwardly and prOJecting it into the intermediate channel in position so that it will engage against the matrices passing therethrough, in case they are assembled in upper position, as shown in Fig. 5, and king" said matrices against forward have been adjusted by position, and when so i 3r position, as shown by will then be free g disk, and will aline therewith, and form a perfect casting. The intermediate channel has a front rail 14 and a back rail 15, provided with the lower and upper grooves 16, 19, and 17, 18, respectively, adapted to receive the corre sponding lugs of the matrices, and to permit said matrices to occupy the upper and lower positions therein.

at Al t1 u ad nste When the filling piecel is thrown out of active position, as shown by dotted lines in Fig. 1, the arm 6 is released and the flexibility of the spring 9 withdraws the pin 10 from looking position in the intermediate channel 13.

What I claim is:

1. In a device of the character described, the combination with a channel, provided for the passa e of the matrices, of a locking mechanism, a apted to be projected into said channel in front of said matrices, and a filling piece which actuates said locking mechanism when in active position.

2. In a device of the character described, the combination'with a channel along which matrices travel to the molding disk,of a locking means adapted to'be projected into said channel, a yieldable'member normally holding said means withdrawn from the channel, an actuating mechanism, and a filling piece operating through-said mechanism, when in active position, to hold said means projected into said channel, in path of said matrices.

3. In a device of the character described, the combination with a channel, along which matrices travel to a molding disk, of a filling piece, an actuating mechanism, a locking means, a member connectedto said locking means and normally holding the same withdrawn from the channel, said actuating mechanism being actuated by the filling piece when in active position and operating against said member to hold said means projected into the channel in front of the matrices, and locking them against movement along said channel.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
